UNITED STATES NUCLEAR REGULATORY COMMISSION
REGION III
2443 WARRENVILLE ROAD, SUITE 210 LISLE, IL 60532-4352 August 21, 2012 Mr. Larry Weber Senior Vice President and Chief Nuclear Officer Indiana Michigan Power Company Nuclear Generation Group One Cook Place Bridgman, MI 49106 SUBJECT: D. C. COOK NUCLEAR POWER PLANT, UNITS 1 AND 2 - NOTIFICATION OF AN NRC TRIENNIAL HEAT SINK PERFORMANCE AND REVIEW OF IMPLEMENTATION OF THE INDUSTRY INITIATIVE TO CONTROL DEGRADATION OF UNDERGROUND PIPING AND TANKS INSPECTION; AND REQUEST FOR INFORMATION INSPECTION REPORT 05000315/2012005; 05000316/2012005
Dear Mr. Weber:
On November 26, 2012, the Nuclear Regulatory Commission (NRC) will begin the onsite portion of the Triennial Heat Sink Performance Inspection and Temporary Instruction (TI) 2515-182 inspection, Review of Implementation of the Industry Initiative to Control Degradation of Underground Piping and Tanks, at your D. C. Cook Nuclear Power Plant, Units 1 and 2. This inspection will be performed in accordance with NRC baseline inspection procedure (IP) 71111.07 and TI 2515-182.
In order to minimize the impact that the inspection has on the site and to ensure a productive inspection, Enclosure 1 is a request for documents needed for the Heat Sink inspection. An information request for the TI 2515-182 Phase I inspection was previously sent on February 6, 2012, and is included here as Enclosure 2 for completeness. The documents for the inspection have been divided into three groups:
- The first group lists information necessary for our initial inspection scoping activities.
This information should be available to the lead inspector no later than October 22, 2012.
By October 29, 2012, the inspector will communicate the initial selected set of approximately 1-2 risk-significant heat exchangers.
- The second group of documents requested is needed to support our in-office preparation activities. This set of documents, including the calculations associated with the selected heat exchangers, should be available at the Regional Office no later than November 14, 2012.
This information should be separated for each selected component, especially if provided electronically (e.g., folder with component name that includes calculations, condition reports, maintenance history, etc.). During the in-office preparation activities, the inspector may identify additional information needed to support the inspection.
- The last group includes the additional information above as well as plant specific reference material. This information should be available onsite to the inspector on November 26, 2012.
It is also requested that corrective action documents and/or questions developed during the inspection be provided to the inspector as the documents are generated. The lead inspector for this inspection is Andrew Dunlop. If there are questions about the material requested, or the inspection, please call Mr. Dunlop at (630) 829-9726. Please send the information to the following e-mail address andrew.dunlop@nrc.gov. A hard-copy with the required information is also an acceptable option.
It is important that these documents be as complete as possible, in order to minimize the number of documents requested during the preparation week or during the onsite inspection.
All requested documents are to be for the time period from the onsite inspection period back to the documents that were provided in response to the previous heat sink performance inspection. If no activities were accomplished in that time period, then the request applies to the last applicable document in the previous time period.
This letter does not contain new or amended information collection requirements subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection requirements were approved by the Office of Management and Budget, control number 3150-0011.
The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid Office of Management and Budget control number.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS),
accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Sincerely,
/RA/
